Fix OP_FMT_none_loc bytecode dumping (#192) 
Commit f404980 ("Add fused get_loc0_loc1 opcode") introduced an
off-by-one (sometimes negative) array index bug because OP_get_loc1_loc1
replaced OP_get_loc0 as the first OP_FMT_none_loc opcode.

Use JS_ToBigIntFree() instead of JS_ToBigInt() (#190) 
Reduces reference count juggling in the happy path and, to a lesser
extent, in error paths.

Fix stack overflow in CVE-2023-31922 (#157) 
isArray and proxy isArray can call each other indefinitely in a mutually
recursive loop.

Add a stack overflow check in the js_proxy_isArray function before calling
`JS_isArray(ctx, s->target)`.

Re-enable stack depth checks under ASan (#161) 
The default 256 kb stack is too small to run some of the test262 tests
when ASAN is enabled.

Double it to 512 kb and ensure threads created by quickjs have big
enough stacks.

bfd8c381cb Add support for building with ClangCL on Windows

699744562e Enable support for GCC compler v < 4.9 
GCCv4.8 and lower doesn't ship with stdatomic implementation
(even though they don't define __STD_NO_ATOMICS__ for c11).
If the code is compiled with GCCv4.8 and older, we use builtin
GCC atomic operations instead.

The patch was initially proposed in quickjs's mailing group:

Handle serialization endianness transparently (#152) 
Change JS_WriteObject() and JS_WriteObject2() to write little-endian
data and update JS_ReadObject() to byte-swap data when running on a
big-endian system.

Obsoletes the JS_WRITE_OBJ_BSWAP flag, it is now a no-op.

Implement static class initializer blocks (#144) 
Spec compliance bug: "await" is illegal inside initializer blocks
_except_ when used as an identifier in a function expression, like so:

    class C {
        static {
            var f = function await() {}
        }
    }

It is somewhat complicated to make the parser understand the distinction
and such code is probably rare or non-existent so I decided to leave
well enough alone for now.

Remove no-op OP_swap+OP_swap bytecode sequence (#143) 
Observed in generated code for static initializers. We could in theory
track and correct it in js_parse_class() but doing it as a peephole
optimization is both easier and more general.
